The Lyrid meteor shower peaks tonight.<\/div>\n
<\/div>\n
The Lyrids are particles shed from comet 1861 G1 Thatcher, which last passed through the inner solar system in 1861. Seen under moonless conditions and perfectly clear sky, the Lyrids usually offers an average peak Zenithal Hourly Rate (ZHR) between 10-20 meteors per hour. Despite the low ZHR, the Lyrids tend to produce bright meteors and occasional fireballs.<\/div>\n
The Lyrids this year peaks tonight at around 9:00 pm Malaysian time. However, the radiant is only rising around 11:00 pm later, and transits around 5:00 am the next morning.<\/div>\n
BAD NEWS: The 74% illuminated waxing gibbous Moon will be up in the sky for most part of the night, brighten up the night sky, obscuring most of the fainter meteors. The Moon will set around 4:00 am.. So, don’t expect to see a lot of meteors throughout the night.<\/div>\n
<\/div>\n
Q: What time should I start observing?<\/div>\n
A: After 11pm. If you could stay up late, around 2-3 am later will the better time, when the radiant is higher up, and the Moon is lower, despite being further away from the peak hour.<\/div>\n
<\/div>\n
Q: Which direction should I look at?<\/div>\n
A: Generally, look at any direction that is clear. If you are observing alone, you may want to concentrate on the sky overhead. If you are observing in group, have everyone cover the different part of the sky.<\/div>\n
<\/div>\n
Q: Do I need a telescope to observe the meteor shower?<\/div>\n
A: No. Meteors appear randomly and move very fast, typically less than 1 second. Just lie down on the ground, have your eyes adapted to the dark sky (do not look at your phone frequently), relax and stare at the starry sky.<\/div>\n
<\/div>\n
Q: Where is the best place to observe?<\/div>\n
A: Any safe and dark place away from the city with minimal light pollution.<\/div>\n
<\/div>\n
Q: How many meteor can I see?<\/div>\n
A: Probably 5 per hour.<\/div>\n
<\/div>\n
GOOD LUCK and CLEAR SKY!<\/div>\n
